GS4A021620FDT

GS4A021620FDT Description

The GS4A021620FDT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications in demanding environments. Housed in an 8-pin narrow SOIC package, this device features four isolated thin-film resistors, each with a 162Ω resistance and a tight ±1% absolute tolerance. Its ±50ppm/°C temperature coefficient ensures stable performance across a wide operating range of -70°C to +125°C, making it suitable for both industrial and automotive-grade designs (though not PPAP or Automotive qualified). The SOIC-C series construction offers superior thermal and mechanical stability, with a 0.4W total power rating (0.1W per resistor) and a 100V maximum voltage rating.

GS4A021620FDT Features

• Isolated Resistor Network: Four independent resistors in a single 8-pin SOIC package, enabling compact PCB layouts.
• Precision Thin-Film Technology: Delivers ±1% tolerance and ±0.5% ratio tolerance for matched resistance values.
• Wide Temperature Range: Operates reliably from -70°C to +125°C with derated power at elevated temperatures.
• Robust Ceramic Case: Enhances durability and thermal performance compared to polymer-based networks.
• Surface-Mount Gull Wing Terminals: Facilitates automated assembly with a 1.27mm pitch for high-density designs.
• Non-RoHS Compliant: Suitable for legacy or specialized applications requiring non-compliant materials.
